h:attr-help is used to define help for attribute whose qualified name is specified in ' attr' attribute. The h:short-help and h:qta-help elements have the same meaning as with element help definition.
<h:attr-help name="myattr"> <h:short-help>...qrichtext-string...</h:short-help> <h:qta-help adp-file="adp-file" href="x.html#otherid"/> </h:attr-help>
Multiple h:attr-help elements may be grouped in h:attr-group elements, and later they can be referenced by h:attr-group-ref's in element help definitions.
